Description
Technical field
The present invention relates to a kind of radiator of the LED of being used for lamp, the built-in radiator that is used for the LED lamp that especially a kind of independence is built-in.
Background technology
In the prior art, the radiating effect of LED light fixture directly has influence on the energy-conservation and efficient of LED lamp, affects the life-span of LED lamp; Generally include lamp holder, lamp body, lampshade on the present LED modulated structure and be installed in driver and the LED illuminator in the lamp body, radiator structure normally is designed with fin on lamp body, and lamp body adopts aluminum alloy materials to be beneficial to heat radiation; And the LED illuminator directly is fixed in the lamp body and lamp body connects, but this structure just relies on aluminium alloy lamp body heat conduction and heat radiation, and the hot-air in the lamp body forms turbulent flow; Can not discharge or discharge difficulty smoothly; Make its radiating rate fast inadequately, thereby influence energy-conservation, the efficient and the life-span of LED lamp, the perforate heat conduction on its lamp body of some LED lamp; Though can discharge hot-air in the lamp body; But because of hot-air forms turbulent flow and is difficult for discharge fast, make radiating effect also undesirable, how to make the radiator structure of LED lamp reach good heat radiating function; Preferably can hot-air in the lamp body be guided, reach quick heat radiating is the technical problem that we need research and solve at present always.
Summary of the invention
The technical problem that the present invention will solve provides a kind of good, quick built-in radiator that is used for the LED lamp of discharging heat radiation of hot-air water conservancy diversion that can make in the LED lamp body.
In order to solve the problems of the technologies described above; The technical scheme that the present invention is used for the built-in radiator of LED lamp is: comprise being fixedly mounted in the LED lamp body lamp body inner chamber is separated into up and down through the outstanding dead bolt of its periphery driving heat dissipation chamber and led light source chamber and at the dividing plate base of its bottom surface fixed L ED light source board; With and diapire is range upon range of together is fixedly mounted on heat radiation cup on this dividing plate base, two-layer at least and that opening makes progress; The sidewall of every layer of heat radiation cup separates formation heat radiation runner mutually; The size of the upper end runner exit sectional area of said heat radiation runner equates with the bottom flow passage sectional area at least; In other layer heat radiation cup diapire of the superiors' heat radiation cup, be evenly equipped with the circle spacing around the center and protruding that be radial extension and cause outside cup that cup is interior, the penetrating outer heat dissipation channel in two ends; The common interior heat dissipation channel that leads to the runner that dispels the heat that forms in the space that every outer heat dissipation channel is separated by in the diapire and heat radiation cup bottom surface, the upper strata that is stacked with it; Described dividing plate perimeter is evenly equipped with power supply lead wire mouth and air guide port; On the LED lamp body bottom and external wall of upper portion circumference of the said driving of correspondence heat dissipation chamber, be evenly equipped with air inlet and exhaust outlet respectively near the surperficial and top heat radiation cup of the air guide port of a dividing plate base top position.
As one of optimal technical scheme of the present invention be: described dividing plate base is a kind of disc type dividing plate base; Be evenly equipped with in the diapire circle spacing around the center and protruding that be radial extension and outside base, cause in the base, outer heat dissipation channel that two ends are penetrating, space that every outer heat dissipation channel is separated by in the diapire and common formation the in heat radiation cup bottom surface, upper strata that is stacked with it towards the interior heat dissipation channel of the runner that dispels the heat.
As two of optimal technical scheme of the present invention be: described outer heat dissipation channel is that the diapire of heat radiation cup is through causing the penetrating bottom recesses in two ends formed to the cup internal projection.
As three of optimal technical scheme of the present invention be: described dividing plate center has a projection, and the center has screw, behind all heat radiation cup closed assemblies, by screw they is fixed on the dividing plate base.
As four of optimal technical scheme of the present invention be: described heat radiation cup is the little truncated cone cup of the big base diameter of a kind of opening diameter.
As five of optimal technical scheme of the present invention be: described heat radiation cup is that the big base diameter of a kind of opening diameter is little, sidewall is the undulatory truncated cone cup of vertical horizontally-arranged.
As six of optimal technical scheme of the present invention be: between the vertical horizontally-arranged ripple of adjacent two layers sidewall of said heat radiation cup be trough to crest, make the heat radiation runner between them form cellular.
As seven of optimal technical scheme of the present invention be: behind described every layer of heat radiation cup closed assembly, it increases progressively the top edge of opening of each layer heat radiation cup highly successively from outermost layer to innermost layer.
As eight of optimal technical scheme of the present invention be: behind described every layer of heat radiation cup closed assembly, it successively decreases the top edge of opening of each layer heat radiation cup highly successively from outermost layer to innermost layer.
As nine of optimal technical scheme of the present invention be: behind described every layer of heat radiation cup closed assembly, the top edge of opening of each layer heat radiation cup causes from its height flat homogeneous of outermost layer to innermost layer.
The invention has the beneficial effects as follows: because the present invention is mounted in the LED lamp body, when the heat that mounted LEDs light source in the lamp body produces when working, built-in radiator of the present invention conducts heat to and drives in the heat dissipation chamber; Cause the hot-air in the lamp body to rise through the discharge of the exhaust outlet on the LED lamp body external wall of upper portion circumference; And the external environment cold air is sucked into through the air inlet on the outer wall circumference of LED lamp body bottom, successively gets in the built-in radiator through air guide port outer heat dissipation channel of importing and interior heat dissipation channel, and every layer hot-air is derived along the heat radiation runner; The size of the upper end runner exit sectional area of heat radiation runner equates with the bottom flow passage sectional area at least; Can let hot-air quicken guiding and flow out, and can avoid turbulization, make hot-air directly rise to the lamp body top; Shed fast outside the lamp through top exhaust outlet; Form hot air circulate discharges of constantly rising, the hot-air derivation is freely suitable, reaches the quick heat radiating effect; So the present invention have the hot-air water conservancy diversion that can make in the LED lamp body good, discharge fast, radiating effect good beneficial effect.
